A RAT for one final time

The autumnal rail adhesion season on the Metropolitan line was supposed to be the last year that London Underground would use the A60 Stock for sandite duties. With the withdrawal of the entire fleet of D78 Stock, two four car units (five car with the sandite car added) have been retained, with two converted sandite cars. The aim being to replace the ageing 50+ year old stock on the Met.

This process was covered in a blog post at the end of last year [2016], however electric, mechanical and paperwork issues with the newly converted D stock sandite trains has meant that the A stock was reprieved for the 2017 season. The set, 5110-5111, was to be kept as a strategic spare for the 2017 leaf fall season but it was never intended to be used.

This year, like last, IS expected to be the last year for the A. This year should in fact, baring a substantial change in events, the very last for the A as it cannot be operation beyond Spring 2018 due to needing a massive and costly overhaul. For London Underground to keep the set active beyond this time they would have to heavily invest in the unit, at a time when they are already investing loads into its replacement.

I wrote a similar blog post around this time last year which covered the switch from A stock to D stock, which at time of writing had not taken place (From A to D but not via C: http://wltmauc.blogspot.co.uk/2016/12/from-to-d-but-not-via-c.html), so this post will purely act as a pictorial summary of really does appear [and in fact did turn out] to be the Metropolitan line's A Stock farewell!

STOP PRESS
On Monday 11th December the unit developed a fault, and upon subsequent inspection at Neasden, turned out to be a significant and costly motor issue. The decision was made from high up within London Underground that the unit would not be repaired and so on Wednesday 13th, A Stock 5110+5111 was officially withdrawn from service after 55 years, and the 2017 RAT season on the Met was terminated.

Two five-car D Stock units will run on the Met for leaf-fall from 2018, one operational unit and a spare back-up.
